VCF NSX 9.1 VPC Networking: Secure, Isolated Private Cloud Enclaves

This article details VMware Cloud Foundation (VCF) NSX 9.1 Virtual Private Cloud (VPC) networking, emphasizing a shift from infrastructure-centric to application-centric network consumption. It explains how VPCs provide isolated, secure enclaves within a private cloud fabric, coordinated through five control layers: workload placement, VPC-to-VPC reachability, external routing, firewall/microsegmentation, and telemetry/operational ownership. The piece highlights support for both distributed and centralized transit designs, with different infrastructure requirements, and discusses how platform teams define reusable connectivity profiles, security guardrails, and IPAM integration. It clarifies that 'intelligent' networking here means policy-driven intent realization, not autonomous AI decisions. The article is relevant for network engineers, cloud architects, and DevOps professionals adopting VCF NSX 9.1 for multi-tenant private cloud environments.
